To all whom. it may concern:

Be it known that I. Siononon B. Connmin,

a citizen of the United States. and a resident of Ferndale, in the county of Whatcoin and State of ll ashington. have invented a new and useful Cow-Hopple-Hook Former; of which the following is a specification.

My invention relates to improvements in cow-hopple hook formers. The covhopple hooks which. my former is desi ned to shape are used to prevent cows from kicking while being milked. A pair of these hopples consists of two hooks connected by a chain of adjustable length. Each hook is engagee with the tendon in proximity to and above the hook with the shank of the hook bearing on the outside of the cows leg' The chain is then adjusted to cause both hook shanks to bear against the cows on the outside thereof. Thus hoppled the cow cannot raise one hind leg alone without causing the hooks to twist on the tendons and cause pain and a sense of helplessness These hopple hooks are made of thin strap iron and hitherto have been shaped with little regard to their properly fitting the leg and their edges frequently have needlessly injured and broken the skin. The object of my improvement is to provide a simple. handoperalole hook former adapted to quickly shape a cow-hopple hook to lit the leg and with outwardly turned edges which can not bear upon the skin.

I attain this object with the device illustrated in the accompanying sheet of drawings, which forms a part of this specification, and in which Figure 1 is a plan view of my hook former, Fig. 2 is a side elevation of Fig. 1, Fig. 3 is a front end elevation of 2, 4 is a plan view of the eccentric pin with handle attached, Fig. 5 is an end elevation of Fig. 4, Fig. 6 is a side elevation of a hopple hook shaped in my former and Fig. 7 is a front end elevation of 6.

Similar characters re r to similar parts throughout. Certain parts are broken away for lack of space or to show other parts hidden thereby.

More particularly: A die plate 8 is adapted for mounting in a vise and has two upwardly-projecting ears 9, opposite each other and bored in line to mount pin 11. On pin 11 is mounted for revolution eccentric clamp roller 66 provided with handle 10. Between ears 9 a hole a is made entirely through plate 8.. The front end of EERNDALE, WASHINGTON.

plate 8 is thickened and grooved and rounded at (3 to serve as die on which a concave hook can he formed. Transversally through this shaped plate end is made hole a large enough to receive the largest part of an eccentric pin. A handle 12 has a bifurcated shank (L12, a. 'lransversally through said shank ends is made a hole. in one end as large as the largest part of an eccentric pin. while in the other end only as large as the smaller part of said pin. An eccentric pin has ends 13 and 6 of equal diameter and concentric while its middle part (r is of larger diameter and eccentric with said ends. End 6 is longer than end 13 and has threaded end 0 adapted to engage a nut 17. On the part of end 5 proxilaate to eccentric body (4 is mounted bushing 14: of diameter equal to eccentric body Between bushing 1d and threaded end o the pin is fitted with key .15 and on this part of end 71 is mounted handle 16 engaged with key 15 and retainable in p ace by nut 17. The end of handle 16 is bent at a and extends as far over eccentric pin body a as the middle thereof. Another hole is made through each of shanks (1/ in line and has an axis parallel with the axis of said holes in said shank ends. In these holes is placed pin 19 on which is mounted for revolution oval shaping roll 18.

in operation: Plate 8 is clamped in a suitable vise, not shown. positioned as illustrated in Figs. 13. Handle 10 is placed horizontally to the rear, handle 12 is set vertically above and handle 16 vertically below shown in full lines'in Fig. 2.

A proper blank A for a hook has its front end made red hot and is placed on plate 8 with its rear end between ears 9 and as far as the rear edges thereof and its front end between shanks a, lying on concave end 6 and extending beyond said plate at the front thereof. Handle 10 is raised to its dotted position at 10 thus forcing eccentric roller (4 down on the rear end of the hook blank and firml Y clamping the same to plate 8. Then handle 16 is carried forward and upward to its dotted position at 16 which movement revolves the eccentric pin and forces shanks (4 to their lowest position in reciprocation at dotted position ll ith said shanks has also moved downward shaping roll. 18 and forced blank A. to conform to the concave shape of the die immediately below said roll 189 Then handle 12 is revolved forward and downward and carries along with it handle 16 the bent end a of which is in its path of movement at (4 Thus as handle :12 is caused to revolve it turns on body a of the eccentric pin and maintains its concentric relation with the concave and rounded end 7f ot the die. By the time handle 12 has reached'its dotted position at 0, shaping roll 18 has moved over the entire periphery of concaveand rounded end and the soft hook blank has been caused to contorm to the shape thereof. Then handle 12 is returned to its full-line position, handle i6 is allowed to remain vertically beneath the plate, handlelO is returned to its full-line position and a tool is inserted from beneath in holed, and caused to bear against the end, a pin mounted for revolution in said h lc havi projecting ends eccentric therewith, a handle hatang a. bifurcated shank the ends ot which i. int'iunted for revolution on said eccentric pin ends, and a shapin g roll mounted tor revolution on! said shankadapted tom-averse said shaped die plate end as said handle is revolved/on said pin. 7'

In a hook. former in combination, a die plate having a rounded concave end adapted for a hook die and a lYQDSYGIi'SG hole therethrmigh concentric with said rounded end, a pin mounted in saidh'ole flior revolu tion having protruding eccentric ends, a

tormin. handle havinn a bifurcated shank the ends of which are mounted tor revolution on said eccentricpln ends, a shaping roll mounted tor revolution onsaid shank adapted totraverse said shaded die and end ass-aid handle is revolved on said pin, and a'pin 'h-ai' dle fixed on one end of SH-Ull eccentric pin adapted to revolve said pin in said plate hole and in said shank ends and having a curved end within the path of said forming handle when the same isrevolved forward whereby sai'd shaping roll is caused to approach said die plate by'r'evolvin said pin handle from aposition beneath said die to a position above the same and said shaping roll is caused to traverse said hook die in its nearest approach thereto as said forming handle together with said pin handle are revolved from a position above said die to a position below the same.

3. In a hook former in combination, a die plate having a rounded concave end adapted for a hook die and a transverse hole therethrongh concentric with said rounded end, a pin mounted in said hole for revolution having protruding ends eccentric therewith, a forming handle having a biturcated shank the ends of which are mounted for revolution on said eccentric pin ends, a,

shapingroll mounted for revolution on said shank adapted to traverse said shaped the plate end as said handle 1S revolved onsaid pin, a pin handle fixed onone of-said eccentric pin. ends adapted to revolve said pin in said die and also in said shankends and having a curved end within the path of said forming handle when the same is revolved forward, and an eccentric roll mounted for revolution ti'ansversally and above the rear end of said die plate having a. handle and adaptmjl to clamp the rear end. ot a hook blank to said die plate, whereby a hook blank havinga red-hot trout end is placed on said die plate, withits rear .end beneath said (.-l:.|.n1pi1u;- roll audits front end betweei'i said bifurcated shank andqprotruding in front thereof when said forming: handle-is in' the vertical above said di-e plate, is clamped, to said die plate by revolving. said cl amping roll: and shaped to conform with said hook form on the front end'ot said die plate by forcing said shaping roll against said blank. by revolving. said pin handle @trom'a vertical position beneath said die plate to a vertical position above-said plate and then revolving said forming. handle and said pin handle. together forward to a positionbeneath said die plate.
